DEVICE FOR HOlST-lNG WELL-BUCKETS.

SPECIFICATION forming part of Letters Patent No. 658,871, dated October2, 1900.

I Application filed July '13, 1900. Serial No. 23,523. (No model.)

To aZZ whom it may concern:

Be it known that I, HYMON HART SIMMONS,

a citizen of the United States, residing at means for elevating bucketsof an elongated form used in small-bore wells with ease by a minimumamount of applied power and to have the several parts under control forad; justment or regulationof movement by a single operator.

The invention consists in the construction and arrangement of theseveral parts, which will be more fully hereinafter described andclaimed. I

In the drawings, Figure l isa sectional side elevation of a device forhoisting well-buckets or the like embodying the features of theinvention. Fig. 2 is a partial longitudinal section of the device shownby Fig. 1, showing the inner portion of the operating mechanism. Fig. 3is a transversevertical section through the winding-drum and mechanismin connection therewith.

Similar numerals of reference are employed to indicate correspondingparts in the several views. 7

The numeral 1 designates a well structure including a roof 2 and aplatform 3. Suspended from the ridge of the roofand depending over thelocation of thewell-curb below is a pulley 4, through which is run arope or cable 5, leading into the well and attached to the Well-bucketand also extending to a drum 6, mounted in a supplemental casing 7,fixed on the platform 3 at one end of the well structure. This drumcomprises opposite heads 8 and 9, connected by bars l0,with

spaces between them for forming an antislipping winding-su rface for thesaid rope or cable. The head 8 has a central socket 11 in the outerportion thereof with an angular opening therein, in which is fitted theinner angular end 12 of a stub-shaft 13, which rotatably extends througha metallic box 14 in the upper portion of one side 15 of the casing 7and also through an outwardly-projecting bearing 16 at the rear end of abracket-plate 17, secured on the outer surface of said side. The saidbracket is shown in full and dotted lines in Fig. l and serves tostrengthen the entire structure and particularly resists the strainexerted by the drum, and on the shaft 13 between the outer face of thehead 8 and the inner side of the adjacent part ofthe cas= ing a flange18 is formed to always keep the said drum-head in proper spaced relationto theeasing. Theoppositehead9alsohasacen= tral socket19 in itsouterface to receivethe end of an adjusting screw-bolt 19, having anouter angular'head 20 and a jam-nut 21, with an operating-wing, and bythis means the drum may be adjusted at will to regulate itssensitiveness and to take up wear. On the outer end of shaft 13 a pinion22 is secured and is in continual mesh with a larger driving-gear 23,mounted on the outer end of stub-shaft 24, carried by the opposite orfront end of the said bracket, the said gear having a crankhandle 25,which, it will observed, is located at the inner end of the said casing.Both the gear and pinion have their axes in the same horizontal planeand pivotally mounted at one end on one of the corner-posts of the wellstructure, as shown by Fig. 2, and projecting inwardly close to theinner surface of the side of the casing on which the said gear andpinion are mounted is a horizontally-disposed brake-lever 26, having anintermediate deflection 27 and a bearing-plate 28 to contact with therim of the drum-head 8, and

thus control the movement of the said drum. The inner engageable end ofthe said lever is located close to the crank-handle for easy reach andquick operation, and secured to the said lever for movement therewith isa metallic strap 29, having its upper extremity loosely bent over theupper edge of the side 15, as at 30, and formed with a book 31, toengage and operate a gravity-paw132, pivoted at its outer end to theupper portion of said side and having its inner reduced end disposed toengage the teeth of the said pinion 22 to prevent backlash or movementof the drum in winding the rope or cable thereon.

The disposition of the driving-gear and pinion meshing therewith in themanner shown obstructs the tendency of said mechanism to slip, and thefunction of the connection between the pawl and brake-lever is toprovide for releasing the said pawl and simultaneously have means in thehand of the operator to control the run-off of the rope or cable fromthe drum and the descent of the bucket into the well without requiringthe separate arrangement and manipulation of unconnected similar parts,and by locating the crank-handle of the driving-gear and the engagingend of the brake-lever adjacent to each other the raising and loweringoperations of the well-bucket can be conveniently and fully controlled.

Many advantages will become apparent as existing in the improvedstructure by the use of the same, and such changes as fall within thescope of the invention will be adopted.

Having thus described the invention, what is claimed as new is- Thecombination with an elevating rope or cable, of an adjustable drum, astub-shaft projecting from one end thereof, a pinion on said shaft, adriving-gear having a crankhandle, the said gear being in continual meshwith the pinion and both the gear and pinion having their axes in thesame horizontal plane, a gravitating pawl to take into the teeth of thepinion, a brake-lever having its inner end adjacent the crank-handle ofthe driving-gearand said brake arranged to contact with one end of thedrum, and a strap attached to the said lever and having an upper hookedextremity to engage the pawl and simultaneously throw the latter out ofthe teeth of the pinion when the brake-lever is operated to contact withthe drum end.

In testimony that I claim the foregoing as my own I have hereto aifixedmy signature in the presence of two witnesses.

HYMON HART SIMMONS.
